[Physio-pathologic aspects of aging--possible influence of physical training on physical fitness].

Two physiological parameters seem to be of major importance in maintaining physical functioning in the elderly: a capacity to perform aerobic exercises (endurance fitness) and an ability to do anaerobic work, especially maximal muscle force and power. Regular physical activity helps in maintaining these parameters at levels enabling normal functioning at everyday's living, contributing therefore to preservation of functional autonomy and independence in the elderly.
